From: Fuller on 21 Jul 2010 09:51 Is there a way to see all the computers on a network? I often connect to hotspots, and I have my own network. In neither case, on WinXP, do I know how to just scan the network to see which computers or shares are on that network. I first tried in Windows XP SP3 but I don't have a "network neighborhood" so I went to the control panel but all it has is network connections which asks me to set up a network. I just want to know what computers and shares are on the network. Looking it up, I found a tool called softperfect network scanner but when I gave it a range of IP addresses around mine it didn't find anything which I find suspect since there were people all around me. Can you point me in the initial direction to run a freeware tool that will just tell me which networks and shares are on the same network as I am?

No Network on the Desktop ? What about through Explorer ? (Just Explorer...not InternetExplorer.)

Not when your wander with your ONE host to connect to a wifi hotspot. You are just one node in THEIR network. > In neither case, on WinXP, do I know how to just scan the network to > see which computers or shares are on that network. So why do you want to hack into OTHER user's computers? If the other hosts are properly configured, you won't connect to them. If the hotspot is properly configured, no host can see any other host. Many routers can be configured to allow any host to have Internet access but none of the nodes on that router can connect to each other. Also, the wifi operator can monitor for any host attempting to scan for other hosts. Firewalls on each host will keep out your attempt to infiltrate their host plus they get alert that someone is attempting to penetrate. > I just want to know what computers and shares are on the network. Yeah, we know you want to invade other user's hosts. None of your business. Besides, if you get caught, you are right there to be identified and the victim (either the wifi hotspot operator/owner or the host owner) can then charge you with [attempted] theft ("breaking and entering" since their host is NOT your property). > Looking it up, I found a tool called softperfect network scanner but when I > gave it a range of IP addresses around mine it didn't find anything which I > find suspect since there were people all around me. Aw, too bad. You can't infilitrate someone else's property. Is this an activity that you actually have time on which to waste? Geez, go get a game to waste your time. > Can you point me in the initial direction to run a freeware tool that will > just tell me which networks and shares are on the same network as I am? Yeah, go ask your local police department as to what are their laws regarding B&E into the property of OTHER people.

What would you like to "see"? Yes. Try a few command line tools. Start -> Run -> cmd <enter> net view arp -a nbtstat -n Getting the IP addresses of everything requires a program. Belarc Advisor (free version) has a nice network scanner built in. More: <http://www.petri.co.il/quickly_find_used_ip_addresses_gui.htm> Nmap will also scan for IP's in use with: nmap -w -sP 192.168.1.0/24 which will produce something like: Host 192.168.1.1 appears to be up. MAC Address: 00:16:01:97:FD:A6 (Buffalo) Host 192.168.1.11 appears to be up. Host 192.168.1.110 appears to be up. MAC Address: 00:01:E6:32:6B:0E (Hewlett-Packard Company) Host 192.168.1.120 appears to be up. MAC Address: 00:24:36:96:13:E6 (Unknown) Nmap done: 256 IP addresses (4 hosts up) scanned in 14.844 seconds >I often connect to hotspots, and I have my own network.

My guess is that you want to attack someone's computer at a wireless hot spot but don't have a clue as to what IP address they're using. If this is the case, kindly reconsider your ethics. If not, kindly disclose what you're trying to accomplish. Most public wireless hot spots have "AP Isolation" or some similar feature that prevents you from "seeing" any of the other users. All you can see if the internet through the default gateway. Packets do not pass between clients (unless specifically routed). The idea is to prevent casual attacks between users, such as spreading a virus. As a side benefit, it also reduces broadcast traffic. >I first tried in Windows XP SP3 but I don't have a "network neighborhood" >so I went to the control panel but all it has is network connections which >asks me to set up a network. Try "My Network Places". If you don't have this icon on your desktop, try: Control Panel -> Display -> Desktop -> Customize Desktop and check the boxes of the icons that your want to see. >I just want to know what computers and shares are on the network. Shares? Are you also looking for open shares so you can drop a friendly virus on their computer? As I previously mentioned, you might reconsider your ethics. At your present ability level, you're almost certain to make a mess. Shares can be found with the "net view" command or with "My Network Places". If you know the IP address, you can also see shared folders with: Start -> run -> cmd <Enter> \\ip_address >Looking it up, I found a tool called softperfect network scanner but when I >gave it a range of IP addresses around mine it didn't find anything which I >find suspect since there were people all around me. That's AP isolation at work. <http://wiki.answers.com/Q/What_is_does_enableing_wireless_client_isolation_help_prevent_in_a_wireless_network> >Can you point me in the initial direction to run a freeware tool that will >just tell me which networks and shares are on the same network as I am?

One semi-legit purpose for "seeing" the other users is that iTunes allows a user to place the local music file into a semi-public directory. That way, if other iTunes users can "see" your computer, they can also play "your" music. (They can't, at least not via the basic iTunes menu, save your music onto their system). I expect this was common knowledge and probably even an advetised feature way back, but I was quite surprised when I hooked up to a public wifi system and saw a dozen sets of iTunes libraries... -- _____________________________________________________ Knowledge may be power, but communications is the key dannyb(a)panix.com [to foil spammers, my address has been double rot-13 encoded] |
